resistance to rice sheath blight的意思|示意

Genetic studies on rice resistance to sheath blight were slow in that ideal resistant resources and effective method to identify resistance to rice sheath blight were short.

由于缺乏理想的抗源、有效的鉴定方法，致使水稻纹枯病抗性遗传研究相对滞后。

The results supported that rice resistance to sheath blight was a hereditable character and selection to resistance was effective.

表明水稻对纹枯病的抗性是可遗传的性状，对抗性的选择有效。

The research was conducted to reveal the regular of resistance to sheath blight and chitinase activities of 13 transgenic rice lines which modified by chitinase gene and other anti-fungal genes.

采用人工接种和酶活性测定的方法，研究转入几丁质酶基因等1～4个抗真菌基因的13个转基因水稻株系对纹枯病的抗性和几丁质酶活性变化规律。
